Pentium 4 LGA775 overheating (possibly)
My computer has been screwed up for a while and I think I know why, but I just want some confirmation. My computer has recently began to get very hot and shut down randomly, which I am almost certain is from an overheating CPU. Recently it won't even get far enough to start up (shuts down after 10 seconds) Here is my question:
In the the retail box, I got the processor and the heat sink. On the heat sink is a small copper circle. When I first installed it, I put thermal paste on the processor and the copper circle, however, I have seen it wearing down. Could my immediate shutdown be from that, or is it possible for the CPU to run fine with no thermal past in between the heatsink and the CPU? Also, there is an extremely high pitched sound coming from my CPU, and I'm not sure what that is (just throwing it in there). My computer boots up and I can see my motherboard bios before it shuts down, which I beleive is not possible with a burnt out CPU (or is it?).
I would really appreciate some help, I don't want to spend money on a new CPU if I don't have to.
